Question

the
speed of the object is 2 m/s ccalculate the mass
of the object when its momentum is 12 kg m/s-
​

Answer 1

Answer:-

Given:-

• Momentum (p) = 12 kg m/s
• Speed of the object (v) = 2 m/s

To Find:-

Mass of the object.

_____________...

We know,

p = mv

➽ m = p/v

where,

• p = Momentum,
• v = Speed (/velocity) &
• m = Mass of the particle.

∴ m = (12 kg m/s) / (2 m/s)

➵ m = 12 kg / 2

➵ m = 6 kgs ...(Ans.)

Answer 2

Answer:-

Given:-

• Speed of the object = 2 m/s (v)
• Momentum of the object = 12 kg m/s (m)

To Find:-

Mass of the object.

___________________...

We know,

m × v = p

where,

• p = Momentum,
• v = Velocity (consider speed in this case) &
• m = Mass.

∴ m = p/v

➵ m = (12 kg m/s)/(2 m/s)

➵ m = (6 kg m/s)/(m/s)

➵ m = 6 kg ...(Mass of the particle)

∴ Mass of the object was 6 kilograms.
